While manmade pollution and other natural emissions are often blamed for their role in global warming, new research from the University of Manchester suggests that they could actually play a role in cooling the world’s climate.

A new study from Columbia Engineering and the Georgia Institute of Technology shows – for the first time – certain volatile organic gases can promote cloud formation in ways atmospheric scientists have never before considered.

Evaluating one way of how clouds can form. To understand this method it’s important to understand a few terms.
The first one is Cloud Condensation Nuclei. The CCN can consist of anything from dust, dirt, salt anything that is floating in the air.
The second thing is moisture. There must be moisture present in the atmosphere to condense on the CCN to form a droplet.
Next step to the process is what is known as collision and coalescence. This is the process of many CCN’s running...

A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
